A field has been partially destroyed after it caught fire in Watford today.

Drone footage shows the scale of the blaze after it broke out in Tolpits Lane at around 4.30pm.

Flames swept across a large swathe of land coming dangerously close to the main road.

There has been a huge emergency response with police cordoning off the area and people being evacuated from their homes.

The fire is on land near Tolpits Lane caravan site and opposite the business park where Camelot is located.

Residents at the caravan park have been led away from their homes and there are reports people at a funfair at King George V Playing Fields were also asked to leave.

Sean Duffy, who shot the footage of the field with his drone, said he could not believe how quickly the fire spread.

The fire is thought to have been brought under control now but a large emergency presence remains in the area.

Tolpits Lane is closed in both directions with police locking down the area with their vehicles and signs.

Hertfordshire Police said this evening: “We are currently assisting the fire and rescue service at the scene of a large fire in a field behind Tolpits Lane in #Watford.

“Road closures are in place and we advise people to avoid the area.”
